MINERS LAMP.

QPECIPICATION forming part of Letters Patent No. 320,287, dated June 16,1885.

Application filed April '7, 1885. (No model.)

To aZZ whom it 11mg concern:

Be it known that 1, HENRY J. Rrcrmnns, a citizen of the United States,residing at ,VilkesBarr, in the county of Luzerne and State ofPennsylvania, have invented certain new and useful Improvements inMiners Lamps, of which the following is a specification, referencebeinghad therein to the accompanying drawings.

My invention relates to improvements in miners lamps, and is designed toproduce a lamp to be attached to the miners hat and burn that product ofpetroleum known as kerosene or coal-oil, without heating the forehead,and thus obviating the deleterious effects common to miners lamps.

The improvement consists, essentially, in providing a miners lamp withan air-duct surrounding the wick tube.

In describing the device, reference is had to the annexed drawings, inwhich Figure 1 represents a side elevation of the lamp, and Fig. 2 avertical section thereof.

The lamp-body is made with an annular oilchamber,A, surrounding aninternal air-chain ber, 13, which extends from the bottom to the top ofthe lamp-body.

Within the chamber B is contained a tube, 0, closed at the bottom andconnected to the oil-chamber by short pipes or passages D.

Near the top of the chamber is provided a hole or holes, E.

Both the inner partition and the outer partition of the chamber A iscontinued upward, as shown at F, and receives a collar, G, on a tube, H,on the interior of which is a continuation of the wick-tube (J. A spaceis left between the tube H and the wick-tube, so that a current of airmay pass from the bottom of the lamp to the burning portion of the wickwhen it is lighted.

The tube II may be secured to the body by means of screw-threads orgrooves on each.

Oil is poured in the inlet I, and fills the chamber A nearly full, thehole E acting as a vent for the contained air. Through the tubes orpipesD the oil is supplied to the wick, which when the lamp is in usefills the tube 0.

A hook, K, serves to secure the lamp to the miners hat.

Heretofore the use of kerosene or coal-oil has been impossible, sincethe heat produced would so heat the forehead of the miner as to producesores or baldness or turn the hair white at the front. The materialusually used is a mixture of paraffine and a black substance, whichprevents a too ready combustion. This substance is expensive andproduces a thick, disagreeable smoke, besides easily clogging the lamp,the cleaning of which consumes valuable time to the miner.

The air duct in the lamp shown in the drawings prevents the heatreaching thehead of the miner and allows the use of kerosene or coaloil,which is inexpensive. The light produced is far superior to thatproduced from parafline, besides burning fora longer time, volume forvolume.

I claim 1. A miners lamp having an oil-chamber, a wick-tube interiorthereto, an air-chamber surrounding said tube, and a removable extensionof both wick-tube and air-chamber, substantially as and for the purposespecified.

2. A miners lamp having an oil'chalnber, a wick-tube interior theretoand connected therewith, an air-chambcr surrounding the wick-tube, an'inlet to the oil-chamber, and a vent therein, and a'continuation 0f thewicktube surrounded by an air-chamber, and removably secured to thelamp-body, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
